The walking axis of a robot is a core component for power transmission and support. RV reducers provide extremely high rigidity, precision, and torque while maintaining a compact size and exceptional reliability, making them an ideal match for the demanding requirements of walking robot joints in terms of load capacity, impact resistance, and precision.

The article explains Nabtesco’s dominance in RV reducers due to its high precision and reliability, while noting that the industry has few suppliers because of extreme manufacturing difficulty. It also briefly mentions competitors like Sumitomo, Spinea, and HONPINE offering cost and delivery advantages.

As a core component of precision transmission, RV reducers are widely used in industrial robots, machine tool rotary tables, automated equipment, and other fields. They are highly regarded for their high precision, high rigidity, and high load capacity. However, for many companies using RV reducers for the first time, selecting the right model from numerous options and parameters often poses a significant challenge. This article will startThey are highly regarded for their high precision, high rigidity, and high load capacity. However, for many companies using RV reducers for the first time, selecting the right model from numerous options and parameters often poses a significant challenge. This article will start with the basic principles of RV reducers, delve into their current status and key parameters, and explain the selection steps in detail, enabling you to easily master the essentials of RV reducer selection. Both beginners and experienced engineers can benefit from this guide.

The RV reducer gearbox is developed on the basis of traditional cycloid planetary transmission. Its reduction structure consists of the first-stage planetary reducer and the second-stage cycloid pinwheel reducer. It uses at least two eccentric shafts to connect the secondary reduction mechanism. The housing and cycloid pinwheel are matched and driven by solid castings and steel components, which form a closed differential gear train. The RV reducer gearbox not only overcomes the shortcomings of general cycloid pinwheel transmission but also has a series of advantages such as high precision (backlash less than 1 arc minute), high rigidity, high durability, high output density (high torque and compact), wide reduction ratio range, and low vibration.
